I meant to qualify my statement that using an inferior switch for the job is a
bad idea as we can now see. I've changed switches in Clippertons that were
arcing a few times before they broke down bad enough to blow fuses. Swan and
Dentron in the 2000L used 12v relays to switch secondary HV and eventually the
contacts pit badly. Just about the only company that did a similar switching
arraignment that did it with proper equipment was Henry amps.

Switching the secondary is not the problem its not using a suitable switch for
the job that is.

I would take the switch out and put a "wire nut" on one transformer
connection sealing it off and make the other connection with another
"wire nut" and test. Then I would switch to the other transformer
connection and test, if both work the switch is arcing.
